BACKGROUND OF THE INVENTION

The invention concerns a device for attaching a tablet computer, in particular, to the rear side of a motor vehicle seat part such as a back rest, head rest or head rest mounting of a vehicle seat.

In contrast to a notebook computer comprising a keypad and a screen block, which are connected via a joint, a tablet computer consists of one single block with integrated flat screen, on which the entries are made via automatically displayed keyboards or with an electronic stylus. The length and width of the block approximately correspond to the dimensions of the 9.7 inch screen and the thickness is slightly more than 1 cm, such that tablet computers are very light-weight, portable devices which are particularly suited for use while travelling.

Despite the very compact design, tablet computers combine a plurality of passive and interactive functions and can therefore be used in an immense variety of ways. The user can e.g. read books and newspapers, listen to music, watch TV programs and video clips, study GPS-based maps, surf on the Internet, send and receive e-mails, communicate via blogs and web forums, play computer games, and also edit photos and documents.

Tablet computers have their own current source and the data is transmitted via radio communication such that neither a power connection nor a connection for data transmission are required for operation. At the most, a power supply must be provided for charging the batteries of the device or in case of a very long period of use.

For all these reasons, tablet computers are also particularly suited for use in vehicles. In particular, during long car trips, the passengers in the backseats wish to watch films, information programs and the news on the Internet or on TV, correspond via e-mail, listen to music or entertain themselves with video games. In particular, for passive use, e.g. for watching films and information programs, it is ideal for the tablet computer to be positioned on the rear side of a front seat approximately at the height of the head rest and for the screen or tablet computer to be aligned approximately in a vertical position to the eye level of the viewer. It is also desirable for the screen or tablet computer to be optimally finely adjusted to the respective user in this passive position of use both in height and also with respect to the angle of inclination.

The position of use of the screen or tablet computer in the passive mode of viewing is, however, unfavorable for interactive use, in particular for making entries via the displayed keyboards. For this purpose, the tablet computer should rather be oriented with the screen facing upwards approximately at table height in a horizontal position or advantageously in a position inclined with respect to the user such that operation is possible in a relaxed position to prevent the user from twisting his/her wrists and fatiguing his/her arms.

In this interactive position of use, it is also desirable for the screen or tablet computer to allow optimized fine adjustment to the respective user both in height and angle of inclination.

Most of the screens have a rectangular shape and are used either in an upright format or a transverse format in dependence on the contents. For this reason, the tablet computer should be rotatable between an upright and a transverse format both in the passive position of use and also in the interactive position of use.

It is also important for the tablet computer to be stably fixed in the positions of use in order to prevent it from changing its position due to shocks, vibrations or acceleration of the vehicle.

Due to their versatility and dependence on an individual person, tablet computers are mainly only temporarily used in a vehicle, like mobile phones, such that mounting and removing thereof to and from the device that is attached to the vehicle should be realized with minimum expense when getting into and out of the vehicle.

The device with and without tablet computer must moreover not endanger the safety of the passengers or limit their freedom of movement and should be quickly and easily mounted to or removed from the vehicle seat in case it is not used.

In another advantageous fashion, the device is not only used in vehicles but also otherwise, e.g. at home or in the office.

It is the underlying purpose of the invention to produce a device for mounting a tablet computer, in particular, to the rear side of a vehicle seat, which enables use of the tablet computer with maximum versatility.

The tablet computer should also be individually adjustable to the users with respect to height and angle of inclination in both positions of use, be stably fixed, and be rotatable between an upright format and a transverse format.

The tablet computer should moreover also be insertable into and removable from the device in a simple and rapid fashion.

The device should moreover also enable easy and rapid mounting to and removal from the vehicle seat and be used elsewhere, e.g. at home or in the office.

The device with and without tablet computer should also not represent any danger for the vehicle passengers.

SUMMARY OF THE INVENTION

In accordance with the invention, these objects are achieved by a device for mounting a tablet computer to the rear side of a vehicle seat part, such as a back rest, head rest or head rest mounting of a vehicle seat comprising the features of the independent claim. Advantageous further developments of the invention are defined in the dependent claims.

The device comprises a fastening device for mounting the device to the vehicle seat part and a carrier element which is movably connected to the fastening device and to which a holder is movably connected for receiving the tablet computer, wherein the holder can be moved between a first position of use, in which the screen of the tablet computer is oriented in an approximately vertical direction facing away from the vehicle seat part, and a second position of use, in which the screen of the tablet computer is preferably oriented in an upward direction and approximately horizontally or at an inclination with respect to the user.

In the first position of use, the holder is advantageously positioned at eye level of the viewers. In another preferred variant, in the first position of use, the angle of inclination of the holder can be adjusted to the viewing angle of the users.

In the second position of use, the holder is adjustable between an approximately horizontal and an approximately vertical position. An inclined position with an inclination of approximately 30° to 60° below the horizontal is preferred.

The holder is preferably positioned in the first position of use substantially above the fastening device and in the second position of use substantially below the fastening device.

In another preferred variant, the holder can also be fixed and used in positions between the first and the second position of use.

A transfer configuration is advantageously provided for displacing the holder from the first to the second position of use and vice versa, which may be designed in different ways, wherein the screen can be aligned to the user in both positions of use.

The transfer configuration thereby comprises a carrier element designed as an arm, which is connected to the fastening device via a first joint and to the holder via a second joint, wherein the two joints rotate about axes that extend parallel with respect to each other and perpendicularly to the rear wall of the holder.

In a preferred further development of this embodiment, an additional pivot bearing is arranged between the first joint and the fastening device, the axis of rotation of which extends in a horizontal direction and parallel to the rear wall of the holder. The movement of the holder between the first and the second positions of use is therefore performed in one plane, the inclination of which is realized through pivoting of the carrier element about the pivot bearing.

The carrier element may be designed to be rigid or in two parts according to the principle of a telescopic slide guidance such that the separation between the joints can be variably adjusted.

The joints and pivot bearings are advantageously held in the respectively adjusted positions through friction or positive fit. Manually detachable locking devices are also preferred, which have a spring-loaded locking bolt and can be unlocked with a release button.

In a further preferred embodiment, ball joints may also be used instead of pivot joints. Combinations of pivot joints and ball joints are also feasible.

Moveable components such as joints and linear guides preferably have an associated locking mechanism for mutual locking thereof. The locking mechanism has an associated element for releasing the locking action.

A further preferred embodiment of the device comprises stops that delimit the angle of inclination of the holder with respect to the user at least in the two positions of use in order to prevent the passengers from being exposed to danger in case of accidents.

The combination of individual features of the described embodiments also produces advantageous embodiments of the transfer configuration.

In a preferred embodiment, the holder can be rotated through at least 90° between an upright format and a transverse format in the positions of use. In a particularly advantageous fashion, the holder can be rotated through 360°, with four locking positions of 90° each.

Towards this end, a pivot joint is advantageously provided between the carrier element and the holder, the axis of rotation of which extends perpendicularly to the broad side of the holder such that the advantageously rectangular holder can be rotated between an upright format position and a transverse format position. The pivot joint is advantageously arranged in the point of intersection of the diagonal of the broad side of the holder such that the holder remains centered with respect to the vehicle seat or its mounting position both in the upright position and in the transverse position.

Locking devices are preferably provided, which fix the holder in a vertical position for inserting and removing the tablet computer into/from the top and in the two horizontal positions, which may additionally comprise stops for delimiting the rotary movement. It is, however, also feasible to provide four locking positions such that the holder is fixed in both vertical and horizontal positions.

The holder advantageously comprises a rectangular rear wall which is directly or indirectly connected to the carrier element at the rear side, e.g. via pivot or ball joints, a guide rail or a carriage, and the size of which approximately corresponds to the dimensions of the tablet computer. The edges of the rear wall advantageously comprise supports, e.g. in the form of continuous or discontinuous end walls, for lateral retention of the tablet computer.

The holder may have a frame which extends parallel to the rear wall and surrounds the screen of a tablet computer that is inserted into the holder. A corresponding opening could be provided at one of the end faces of the holder for inserting and removing the tablet computer, or the frame may be connected to the holder via a hinge such that it can be opened for inserting or removing the tablet computer.

In one preferred embodiment, instead of a frame, only L-shaped clamps may be arranged on two opposite supporting walls, which surround the tablet computer on the sides of the screen and hold it down with respect to the rear wall, wherein one of the clamps should be movable to the outside, preferably in a spring-loaded fashion, for inserting and removing the tablet computer.

A continuous peripheral border is particularly advantageous, which approximately corresponds to the height of the edge of the tablet computer or projects past it. This border is advantageously provided with an outward safety radius and may consist of an elastic material.

In order to increase the solidity and provide large safety radii, the edge may be designed as a double-walled U that is closed on the side of the screen.

In a preferred embodiment, a concave receiving pocket is arranged on one side of the border, into which the tablet computer is disposed and is subsequently pivoted below the spring-loaded holding clamp arranged on the opposite border.

The rear wall of the holder preferably has openings to facilitate removal of the tablet computer from the rear of the holder following release of the holding clamps.

In a preferred embodiment, a spring arrangement is provided, which lifts the tablet computer when releasing the holding clamp to such an extent above the border that the tablet computer can be conveniently grasped and be removed from the holder.

In another preferred embodiment, the rear wall of the holder has recesses such that the tablet computer can be pushed from the rear out of the holder after releasing the holding clamps.

The holder advantageously comprises a plug for transmitting current and/or data, which, when the tablet computer is inserted, is coupled to a mating connector provided on the tablet computer.

In an alternative variant, only an opening may be provided at a corresponding location of the border of the holder, through which plugs for current or data can be directly coupled to the tablet computer. It would also be feasible to similarly provide an opening for the jack plug of an earphone at a corresponding location.

In order to ensure easy and convenient operation of the push-buttons that only slightly project past the end faces of the tablet computer despite a broad safety border of the holder, in one preferred embodiment of the invention, transfer buttons may be provided, which are guided in the border of the holder and transfer the pressure via a plunger, from the outside to the keys arranged on the tablet computer. The transfer buttons are advantageously returned via a separate spring which is formed on the key or can be a separate part.

The fastening device may be rigidly or movably connected to the vehicle seat part or be later mounted to a vehicle seat part by the user of the vehicle.

The inventive device is suited both for installation in a receiving space arranged on the rear side of a back rest or a head rest, and also for mounting to a corresponding fastening device which is provided or can be mounted to a back rest, a head rest or a head rest mounting.

In a preferred embodiment, a fastening device is provided for mounting the device to the columns of a head rest. This enables later installation into almost any vehicle without requiring any structural provisions on the part of the vehicle manufacturer.

The device is advantageously connected via a detachable coupling to the vehicle seat part and can be mounted to and removed from it in a simple and rapid fashion depending on the requirements. It is thereby advantageous for the device to be foldable into a compact shape for storage.

In accordance with a preferred embodiment, the coupling comprises a locating bushing into which a connector element, which can be folded out from the carrier element, can be inserted and locked.

The device also advantageously abuts the vehicle seat part as flatly as possible and minimally limits or obstructs the freedom of movement of the passengers.

In a preferred embodiment, the device may be installed in a receptacle formed on the rear side of the back rest or a head rest such that the device is accommodated in the first position of use substantially in the body of the vehicle seat part, and the screen of the tablet computer is approximately aligned with the outer side of the vehicle seat part.

For rotating the holder or the tablet computer between an upright format and a transverse format and/or for inserting and removing the tablet computer and for moving the holder or the tablet computer into the second position of use, the device or the holder may be moved to a correspondingly large extent out of the receptacle. This could be realized e.g. through extension with a linear guidance, a pivot joint or a telescopic axis of rotation.

The head rest columns, via which the head rest is connected to the back rest of the vehicle seat, are particularly suited for later assembly. In a preferred embodiment, a clamping element may be clamped between the two head rest columns, to which the device is rigidly or detachably connected.

The device is preferably fastened via a detachable coupling to a locating bushing disposed on the clamping element and to a connector element that is inserted into the locating bushing and can be locked with a locking device. In this embodiment, the first joint is advantageously arranged on the connector element.

In a further preferred embodiment variant, the device has a second fastening device which also enables use of the device outside of vehicles, for example at home or in the office. The second fastening device is advantageously designed for use of the device on a table area, and comprises an identical locating bushing for the connector element arranged on the device, such as the fastening device in the vehicle, such that the device can be coupled to the two fastening devices in the same fashion and be used both in the vehicle and at home or in the office.

A second fastening device of this type is advantageously provided with a suction holder with round rubber pad, with which the fastening device can be mounted by generating a vacuum on a table area or on a wall or a window pane.

In one preferred embodiment, a second fastening device of this type comprises a round base in which the suction holder and an eccentric lever are housed for generating the vacuum by lifting the rubber pad, and a hood that is rotatably connected to the base and houses the locating bushing. This enables additional rotational movement of the device of 360° about an axis of rotation that is aligned perpendicularly to the fastening plane.

In a further embodiment, a mounting foot of a preferably elastic material is provided, which can be mounted to the connector element of the device such that the device can also be set up on a flat base outside of vehicles in a non-displaceable fashion. The mounting foot preferably has a T-shape and has lateral supports such that the device is stably supported in an upright format and in a transverse format of the holder.

Further advantages and designs of the invention can be extracted from the description and the attached drawings.

It is clear that the features mentioned above and below can be used not only in the respectively stated combination but also in other combinations or individually without departing from the scope of the present invention.

The invention is described below by means of preferred embodiments with reference to the attached drawing.

 DESCRIPTION OF THE PREFERRED EMBODIMENT

FIGS. 1 through 6 show a first variant of the device with a first embodiment of the transfer configuration. The height-adjustable head rest 1b with head rest columns 1c′, 1c″ is mounted to the back rest 1a of the vehicle seat 1. A spring-loaded clamping element 2a is inserted between the head rest columns 1c′, 1c″. A locating bushing 3a is arranged in the center of the clamping element 2a, into which a connector element 3b is inserted and locked in the locating bushing 3a by a locking device 3c that can be released via lateral buttons.

A first joint 7 is arranged at the rear end of the connector element 3b, to which joint one end of a carrier element 4 is hinged. At the other end of the carrier element 4, a rear wall 5c of a holder 5 is connected via a second joint 8 to the carrier element 4. The axes of the first joint 7 and the second joint 8 extend parallel to the rear broad side of the back rest 1a or the head rest 1b.

A pivot joint 5a is arranged between the second joint 8 and the rear wall 5c of the holder 5, the axis of rotation 5b of which extends perpendicularly to the broad side of the rear wall 5c. The pivot joint 5a is arranged in the point of intersection of the diagonals of the rear wall 5c, such that the holder 5 can be rotated between an upright format and a transverse format and maintains central alignment with respect to the vehicle seat 1. Release of the device is thereby not required.

The first joint 7 and the second joint 8 are designed as friction hinges such that the respective settings of the carrier element 4 and of the holder 5 are maintained.

FIG. 6 schematically shows the device in three different positions. The first view shows the holder 5 in the first position of use. The view in the middle shows an intermediate position of the holder 5 and the last view shows the holder 5 in the second position of use.

FIG. 1 shows the structure of the holder 5. The supports 5d″ and 5d″″ in the form of side walls, which are arranged at right angles, are mounted to the two short front edges of the rectangular rear wall 5c. At the long lower front edge (FIGS. 1 and 2), the support 5d′ is designed as an L-shaped side wall and forms together with the supports 5d″ and 5d″″ a pocket into which the tablet computer 6 is put during insertion into the holder 5 and can then be pivoted towards the rear wall 5c. The supports 5d″, 5d″″ thereby laterally center the tablet computer 6 such that, during insertion into the holder 5, the connector 5f that is arranged in the center on the inner side of the support 5d′ for transmitting current and/or data is coupled to the mating connector arranged on the tablet computer 6.

The clamp-shaped support 5d′″ is arranged at the front edge of the rear wall 5c opposite to the support 5d′, is pressed by a spring (not illustrated) against the tablet computer 6, and can be drawn past the edge of the rear wall 5c for pivoting the tablet computer 6.

FIG. 7 shows a second variant of the with a second embodiment of the transfer configuration, in which the carrier element 4 comprises a carriage 4a connected to the first joint 7, which forms a linear guidance together with a guide rail 5g arranged on the holder 5, the linear guidance displacing the holder 5 relative to the first joint 7. The first view shows the holder 5 in the first position of use. The center view shows an intermediate position of the holder 5 and the last view shows the holder 5 in the second position of use.

The first joint 7 is also designed as a friction hinge in this second variant such that the respective setting of the holder is maintained. A pivot joint 5a is also arranged between the carrier element 4 and the rear wall 5c of the holder 5, the axis of rotation 5b of which extends perpendicularly to the broad side of the rear wall 5c (FIG. 5).

FIGS. 8 through 16 show detailed views of the second variant of the device in accordance with FIG. 7. The joint bearing 45b of the carriage 45 is connected via the joint 70 to the connector element 30b. The carrier element 40′ comprises a guide rail 40a in which the sliding plate 45a of the carriage 45 is movably and linearly guided, wherein the displacement path is limited by the end stops 40a″ (FIGS. 10 and 11).

Locking recesses 40h are arranged on the inner sides of the two side walls of the guide rail 40a, into which locking cams 45f engage, which are laterally connected to the sliding plate 45a via spring elements 45e and retain the carriage 45 with positive fit. During displacement of the carriage, the spring-loaded locking cams 45f act between the locking recesses 40h as brakes by means of frictional locking (FIGS. 14 and 15).

The first bearing seat 40c is arranged in the center of the guide rail 40a and forms together with the second bearing seat 50k, which is arranged in the center on the rear wall 50a of the holder 50, the pivot joint 5a that rotates about the axis of rotation 5b. The two bearing seats 40c, 50k, and thereby the carrier element 40 and the holder 50, are held together by the connecting pin 50n that is snapped with the connecting sleeve 40g. The pivot joint 40c, 50k, 40g, 50n is covered by the joint cover 40b which is concentrically mounted to the guide rail 40a and laterally projects past the guide rail 40a and stably supports the holder 50 and the carrier element 40 with respect to one another during rotation of the holder 50. An arc-segment shaped stop 40d is arranged concentrically with respect to the first bearing seat 40c and an arc-segment shaped counter stop 501 is arranged concentrically with respect to the second bearing seat 50k, the arc lengths of which correspond to a central angle of 90° and which are opposite to each other when the holder 50 and the carrier element 40 are vertically aligned such that the holder 50 can be rotated with respect to the carrier element 40 from the vertical position to both sides through 90° to each side.

A receiving sleeve 40e is disposed vertically above the axis of rotation 5b on the side of the guide rail 40a facing the holder 50, into which a spring-loaded ball catch 40f is inserted. On the side of the rear wall 50a facing the carrier element 40, three hollows 50p′, 50p″, 50p′″ are mounted into which the ball catch 40f locks in the vertical and both horizontal positions of rotation of the holder 50 and fixes the holder in the respective positions.

The length of the guide rail 40a corresponds to the height of the rectangular holder 50 in its vertical position in the upright format. When the holder is pivoted into the horizontal position to a transverse format, the guide rail 40a symmetrically projects past the holder 50 at the top and bottom (FIG. 12).

The pivoting angle of the guide rail 40a about the first joint 70 is delimited by the two stops 45c, 45d on the carriage 45. The first stop 45c is used to delimit the inclination of the holder 50 or of the tablet computer 60 with respect to the user in the first position of use, whereas the inclination of the holder 50 or tablet computer with respect to the user in the second position of use is delimited by the second stop 45d on the sliding plate 45a (FIG. 14). In both positions of use, the holder 50 can freely move away from the user towards the vehicle seat part 10a, 10b.

The connector element 30b can be stored using little space by pivoting it around the first joint 70 into the guide rail 40a (FIG. 13).
